Alternate version, for programmers only: using any language (BASIC, C, Excel, whatever) find the maximum of A, B, and C, but be careful when writing the program, because you cannot use the ">" key, for it's broken (thus writing things like IF A>B is impossible...) and you cannot use the "M" key either, for it's also broken (...and writing H=MAX(A,B) is also not possible.)
